Question

C. Complete the following combustion reaction. Write your balanced equation two different ways.

Answer 1

Required Answer:

The substance in reactants side shows a alkane which is burnt. As a result of combustion, Carbon dioxide and water is formed.

The equation will be like this:

$\rm{ C_8H_18 + \dfrac{25}{2} O_2 =8 CO_2 + 9 H_2O }$

Now here we can see that the stoichiometric coefficient is a fraction, hence Multiplying 2 in both sides of the eq.

$\rm{2 C_8H_18 + 25 O_2 = 16 CO_2 + 18 H_2O }$
